MACHINE FOR MAKING HAT-BODIES.

Specification of Letters Patent No. 31,053, dated January 1, 1861.

. The same letters indicate like parts in both the figures.

The object of my invention is to make hat bodies of fibers which havebeen obtained from the disintegration of fur and other felts bycombiningsuch disintegrated fibers with a sheet or web of fibers asdelivered from a carding engine. And to this end my said inventionconsists in the employment of a picker and its appendages for receiving,

picking, and throwing the fragments of fibers obtained from thedisintegration of fur and other felts in combination with the doffer ofa carding engine, which delivers a bat of carded woolen fibers, and withwinding cones on which the bat so formed is wound into hat bodies, bymeans of which combination the bat of carded fibers as it passes fromthe doffer of the card to the cones is covered with'the disintegratedfibers from the picker which become incorporated therewith.

In the accompanying drawings (a) represents a doffer by which a bat ofcarded wool fibers is delivered from any suitable carding engine, whichbeing well known it is not necessary to represent or"describe.V As thebat of carded wool fibers is-delivered by the said doffer it passes toand is wound upon a pair of rotating and vibrating cones (b) constructedand operated in manner well known to hat manufacturers, and whichthereforeit is not necessary to describe and represent.

In the upper part of the frame there is a picking apparatus whichconsists of a feeding apron (c) on which is to be placed the fibroussubstance obtained from the disintegration of fur and other felts by aprocess invented by me and described in Letters Patent granted to myassignee, Samuel B. Tobey, and bearing date the 12th day of April, 1859,or by any other process producing similar results. The material soplaced on the feed apron is presented regularly to a pair of feedrollers (el, d), which in turn present it to aA rapidly rotating picker(e), by which it is loosened and thrown and scattered within asurrounding case This case is in the form of a hollow semicylinder asrepresented, and one edge of it extends over the feed rollers, and theother edge (g) extends down in a tangent to form the outside of avertical spout (h) extending down to within a short distance of theupper surface of the bat of carded fibers as it passes from the dofferto the winding cones.

The axis of the picker is midway between the inner edge of the spout (h)and that edge of the cap case (f) which extends over the feed rollers,so that the circle of this cap is eccentric to the picker. And withinthe cap there is a plate which I denominate a break current, whichextends in a curve from the inner periphery of the cap to within a veryshort distance of the picker, so as just to clear the teeth. The underpart of the picker is inclosed by a bottom case open as at (l) back o fthe picker for the admission of air, and in the front part of the saidcase there is an inclined defiector (m), which I prefer to makeadjustable. This is simply an inclined plate the ends of which areadapted to slide in suitable grooves in the ends of the case (7c), andits upper edge is in close proximity with the inner edge of the spout(71,), leaving an open space between its upper edge and the lower edgeof the break current (j), through which alone the material thrown by thepicker can reach the spout, so that it shall descend the said spout in asort of shower to fall onto the bat of carded fibers. In this way Ieffectually break the current of air, which otherwise would have aninjurious effect on the bat of carded fibers below, and deposit thedisintegrated fibers regularly on the bat of carded fibers.

lVhat I claim as my invention and desireV the break current plate in thecap case over to secure by Letters Patent isthe picker and thedeflecting plate substanl.
